New laser 25X more powerful in mid-infrared | Gizmag
“The erbium-doped zirconium-fluoride-based glass fiber laser operates in the mid-infrared frequency range, which is the range where many hydrocarbon gases absorb light. The laser can produce 25 times as much light as lasers operating at a similar wavelength according to the researchers, paving the way for the detection of previously obscured, low concentrations of gases.”
Robotic applications could include detecting the condition of soil and plants by means of the hydrocarbon compounds which persist in higher concentration below the leaf canopy than above it, for example the early detection of mold or anaerobic conditions.
